In order to test sockjs server implementation the server needs to provide a standarized sockjs endpoint that will can used by various sockjs-related tests. For example by QUnit or Sockjs-protocol tests.
This small code does exactly that - runs a simple server that supports the following SockJS services:
/echo/disabled_websocket_echo/cookie_needed_echo/close/ticker/amplify/broadcast
If you just want to quickly run it:
node server.js
